Abstract
In an apparatus for connecting two workpieces together by welding, the workpieces lie on supporting surfaces and are butted together at their edges to form a butt joint. The workpieces are subjected to pressure on the side opposite to the supporting surfaces. At least one supporting surface is capable of yielding under pressure, and, in so doing, changes its position in relation to the butt joint, so as to reduce any gap between the workpieces.
